To all whom it may concern: V

Be it known that I, CHARLES M. STANLEY, a citizen of the United States, residing at Hamilton, in the County of Butler and State ot Ohio, have nvented new and. useful Improrements in Turn-Tables, of which the following is a specication.

My inprovements relate to turntables used in connection With water-chutes, and

having tilting cradles on which boats are' alternately received and discharged. In these constructions heretofore the tilting of the cradles has been accomplished by mechanisn, usually operated by hand, independently of" the mechanism and driving power enployed to turn the tableitself; `'which not only entails additional mechanism, but con-` narily, in a turntable providedwith suit-' able means for its -rotation and with pivoted cradles for the beats, combined with an 1ndependent crcular nclmed track-Way `by and upon which the cradles are upheldor depressed according' to their radal position in relation thereto,-by meansof supporting wheels or rollers attachecl to the cradles and running upon said track way,-the oscillating movements of the cradles, due to gravity,

being incidental to the general' rotative movement of the turn-table. j

In connection with the main improvemets iudicated-but not a necessary feature in a r;sos. --T may also employ a system of catches by which t c adle carrying the outgoingboat is temporarily upheld, independently of its relation to the supporting track-way, until it reaches the radial position of discharge upon the down-chute; whereupom by the Withdrawal of said watches, the cradle is allowed to drop by' grayity to its supporting track and into connection with the down-chute, thereby giving, an added mpetus to the boat ,discharged -from said Cradle.

My invention is illustrated in the accom-- panying drawings, in which Figure 1-- is the general plan view of a turntable showing the relative position of the cradles in relation to the receiving and discharge trackways. F'g. 2 is a detail elevation of the lever conncctions employed for releasing the catches 'to drop the cradles and clischarge a boat upon the down-chute. Fig.

3- is a side elevaton of'the turn-table, showi ing the relation of the cradles to the supporting trackway; and Fig. 4- is a front ele vation of the turntable showing the relation of the discharging cradlc in full lines When upheld by the catches; and in dotted lines When released from the catches. v

Referr'ing nowto the drawings, in which only such parts are shown are necessary .to illustrate my invention, A- designates a turntable of ordinary Construction "which revolves about a central pivot 79, upon a circular trackway, a, through the medium of a concentric system of roll ers a running thereon and upon which the turn table immediately' Tests. suitable mechanism 'is providecl for the rotation ofthe turn-table as required, and catches for stopping it a't proper points g-'all .of which' being connnon in this class of devices is not here shown.

Upon the top surface ot' the turn-table frane are carried two cradles B l, or track-secti'ns, for the acconn'odatio' of boats drawn up one chnte ortaekway C and discharged upon another (3 usually parallel thereto. ;These cradles are duplicates of each other, arranged parallel and equidis tant from the center of the turn table, each one being pivotally Secured to the turntable, as at bkb near the receiving end of the Cradle, and the franing of the turn table being arranged to allow the forward or discharging end of the eradle to drop to the depressed position indicated in Fg. 3, when discharging its boat; Each Cradle is provided at its discharging end (the end most turn table) With a bracket or strut (l pivoted to have suticient play to hang always vertical in' any angular position of the cradle. The braclet carries pivotedi at its lower ex` tremity a cross bar d at the extremities of renote from its pivotrl connection with the which are journaled double tlanged rollers Substantially concentric with the trackwayc, and inline beneath the' struts d, at

registry with the down-track of the main,

chu'te, the trackway e is depressed, with gradually curving in'clines connect'ng at registry with said down chute.

each side with the normally level portion;

-so that, as the rotation of the turn-table is continued, the cradle containing the outgoing boat is depressed by gravity as it apl proaches the point of registry with the down chute, because its supporting wheels carred upon its su porting strut or bracket,

ride down the inc ineof the curved track'- i way to the point of extreme depression in This movement of the cradle, it will be observed, is effected solely by gravity i-n 'the general rotation of the turn-table, as an incident thereof. In like manner, when the boat is discharged from the Cradle to the down-chute,

and the turntable is. further rotated in continuation of its former movement, the wheels supporting the depressed end of the Cradle ascend the opposte 'incline of the' supporting trackway and the cradle is returned to and thence continued in its normally hori- 'cradles registering with chute connecting with the turn table at different elevazontal position as. part of the turn-table. 'As thus construeted andused, the boat on coming from the up-track c upon. the approp'riate cradle, to its.limt of movement,

is made fast upon the Cradle by any suit: able catch oi' astening (not s own) and released when the turn table has rotated 180 degrees, and the said Cradle has. become 40 depressed in'the nanner describechand registers with the down chute. The -fastening being released, the boat isallowed to descend the chute c by gravity. I may, however, employ a ddvice for the purpose of holding the Cradle temporarily in its normally horizontal position against gravity, notwithstanding the depression in its supporting trackway at the point of registry with the down-chute. This consists of two bolts f f arranged to slide in suitable soekets on the framing of the turn table at opposite sidesot' the cradle and so connected as to be simultaneously moved inward beneath and become temporary sup orts for the cradle, or withdrawn outward so as to 'allow the Cradle to drop by gravity toits inclined position, when in registry With the down chute. Mechanism for this purpose is. illustrated in Fgs. 1, 2 and 4:( Bolts f f are passed through correspondingly forn'ed sockets in the framing at the sides of and beneath the Cradle as sup ports at each side,

as indicated in Fig. 4. The outer ends of the bolts are perforated for connection with levers g g of the first and second class respectively, which are suitably fulcruned at g 9 and connected by an Operating rod 9 The bolt f at one side is votally connected to one arni of bell cranii lever L (see Fig, 1 whose 'other arm is connected to a pushrod h extending. outwa'ol to the outer side of the turn table, as shown, where it maybe actuated by a hand-level j adjacent to the turn table, when the latter is in proper i position for discharging the outgoing boat. The bolts f* and f are provided with springs 8, wher'eb they are held normally inward to uphol of the hand level' j. When the cradle drops .to its lowest position, the bolts f and f rest against the sides of the cradle and. are thus held apart until the cradle`is restored to its normally 'horizontal position, when they automatically return to position.

' Arranged as hereinbefore indieated, the

looking action of the catches is entirely automatic, and, 'like the oscillation of the cradles, is incidental to the rotation of the turntable ti v I claim as my invention, and desire to secure by Letters Patent of the United States z l. A turntable provided with pivoted tions, and means for clevatin'g and depressingI the-cradles, actnated by rotation of the ta e. i i

2, The conbination of 'a turn-table; trackwavs, or chutes, connecting-therewith at different elevations; an independent circular trackway surrounding the base of said turn-table; and cradles pivoted to'and adapted to oscillate upon-the turn-table' structure, provided with Wheeled supports restin on said independent circular trackway, an by rolling contact upon suitably d sposed inclines of said trackway, registering the cradles with the connecting tracks o' chutes at their several elevations, i

3, In a turn-table' provided with pivoted cradles and an incl'ined `su porting trackway, a system of catches libi' maintaining the cradles in horizontal position against the force of gravitv, with means for releasing the same at wi 4 In testimgny whereof I have hereunto set my hand inpresence of two subscribing witnesses.
